Claims (1)

  1. 체결부재(18a),(18b)가 서로 맞닿을 때까지 유압구동의 체결부재(18a),(18b)가 피처리재에 압력을 가하여 변형시키는 공구에 있어서, 체결부재(18a),(18b)가 서로 맞닿은후에 승압되어 일정압력에 도달하면 유압을 개방하는 릴리이프 밸브 (30)를, 공구본체의 재질보다 단단하고, 또한 공구본체에 대하여 붙이거나 페기가 자유롭게끔 구성함과 동시에, 상기 유압을 개방하는 일정압력을 가변적으로 설정할 수 있도록, 릴리이프 밸브(30)의 스프링(44) 압력을 외부로부터 조절가능하게 구성한 것을 특징으로 하는 유압식 체결공구.
